APPLICATIONS INFORMATION
SERIAL INTERFACE TO MULTIPLE AD5530s OR
AD5531s
OPTOCOUPLER INTERFACE
In many process control applications, it is necessary to provide
an isolation barrier between the controller and the unit being
controlled. Opto-isolators can provide voltage isolation in
excess of 3 kV. The serial loading structure of the AD5530/
AD5531 makes it ideal for opto-isolated interfaces because the
number of interface lines is kept to a minimum.
SYNC
shows a 4-channel isolated interface to the AD5530/AD5531.
To reduce the number of opto-isolators, if simultaneous
updating is not required, then the LDAC pin can be tied
permanently low.

Figure 26. Opto-Isolated Interface
Figure 27 shows how the
pin is used to address multiple
AD5530/AD5531s. All devices receive the same serial clock and
serial data, but only one device receives the SYNC signal at any
one time. The DAC addressed is determined by the decoder.
There is some feedthrough from the digital input lines, the
effects of which can be minimized by using a burst clock.

DAISY-CHAINING INTERFACE WITH MULTIPLE AD5530s OR AD5531s
A number of these DAC parts can be daisy-chained together using the SDO pin. Figure 28 illustrates such a configuration.
